Description

[Detailed Description of the Invention] Industrial Application Field The present invention provides a receiving gutter within a sorting cylinder which has a large number of potholes formed in its inner circumferential surface, is supported by a plurality of rollers, and is rotatably suspended horizontally. This invention relates to a rotary sorting machine that sorts mixed grains by inserting it horizontally.

Particularly, the present invention provides for easy cleaning and inspection of the sorting barrel and the inside of the machine by configuring the sorting barrel so that it can be inserted and removed from the outside of the machine. The idea was to make the aircraft extremely convenient while reinforcing and making it more solid.

Conventional technology As mentioned above, mixed grains are collected by inserting a receiving gutter into the sorting barrel, which has a large number of holes formed in its inner peripheral surface, is supported by a plurality of rollers, and is rotatably suspended horizontally. A conventional rotary sorting machine for sorting grains in which the sorting barrel is removable from the outside of the machine has a structure as shown in, for example, Japanese Utility Model Application Publication No. 108182/1982. The sorting cylinder is configured to be able to be freely inserted and removed from the receiving trough, but when the sorting cylinder is removed from the rear wall side and inserted from the rear wall side, the sorting cylinder is inserted and removed from the machine body. The structure is not easy, as there is no member to support it, and it takes a lot of effort and time to insert and remove it.

Problems to be Solved by the Invention Therefore, the present invention solves the problem that, as mentioned above, in the case of the conventional structure, it is not easy to insert and remove the sorting cylinder, requiring unnecessary labor and wasting time. It was created with the aim of solving this problem, making insertion and removal extremely convenient and efficient, making it easy to clean and inspect the sorting barrel and the inside of the fuselage, and reinforcing the fuselage to make it more solid.

Means for Solving the Problems The present invention is constructed as follows to achieve the above object.

That is, a receiving gutter is inserted into a sorting barrel which has a number of potholes formed in its inner circumferential surface, is supported by a plurality of rollers, and is rotatably suspended horizontally, and the sorting barrel is pulled out from the machine body. In a rotary sorting machine configured to be freely configured, a guide rail is horizontally installed below the sorting cylinder along the sorting cylinder,
The guide rail connects the front wall and rear wall of the fuselage.

Function: If you pull out the sorting barrel, which is rotatably supported by multiple wheels, when you take it out of the machine or insert it into the machine, you can pull it out while holding the sorting barrel, and it will come out of the state where it is supported by the wheels. At the same time, the sorting cylinder is supported by the guide rail, and when it is further pulled out from this supported state, the sorting cylinder is slid on the guide rail and guided out of the machine.
This makes it easier to clean and inspect the sorting barrel and the inside of the aircraft. Further, after this cleaning and inspection is completed, when the sorting cylinder is supported by the guide rail and inserted, it slides on the guide rail and is supported by the rollers at a predetermined position so that it can be operated.

Moreover, on the other hand, the body is reinforced by the guide rails and becomes solid, so that the sorting barrel can rotate smoothly.

EXAMPLES The present invention will be specifically explained below with reference to the drawings of examples. Since the rotary sorting machine shown in this example figure is installed in a hulling machine to sort out mixed rice of brown rice and paddy after deairing and sorting, let us first explain the outline of this hulling machine.

A is a removing part, B is a wind sorting part, and C is a rotary sorting machine according to the present invention. It is integrated with the top to form a huller.

The removing section A consists of a paddy tank 2 and a pair of removing rolls 3, etc., and the wind sorting section B is equipped with a suction dust remover 4 and a pressure air fan 5 at the front and rear, and the suction side of the suction dust remover 4 and the pressure air fan 5 are installed at the front and rear. A sorting air passage 6 and 7 is formed on the front and rear sides in communication with the blowing side of the fan 5, and in this front side sorting air passage 6, the scraped material from the removal section A is sorted to remove dust such as paddy grains, etc. The rice grains are removed to obtain a mixed rice of brown rice and paddy, and the brown rice sorted by the rotary sorter C is air-sorted in the rear sorting air passage 7 to remove waste rice.

The rotary sorting machine C is housed in a sorting cylinder 11 which has a large number of potholes 8 formed on its inner circumferential surface and is rotatably mounted horizontally by a plurality of pairs of wheels 9, 9 and 10, 10 at the front and rear. Two sorting sections C1 and C2, which are horizontally inserted through the receiving gutter 12 and the supply gutter 13, are disposed above and below, and the mixed rice of brown rice and paddy obtained at the front side of the wind sorting section B is separated into brown rice and paddy in each of them. It is configured to be selective.

Therefore, to describe the communication means of each of the above parts, 14 is a mixed rice distribution box, and its lower part is branched, one side communicates with the supply gutter 13 of the upper sorting section C1, and the other reaches the bottom of the lower sorting section C2. supply gutter 13
15 and 16 are brown rice takeout gutters,
The brown rice takeout gutter 15 communicates with the upper receiving gutter 12, and the brown rice removing gutter 16 inherits the brown rice taken out from this brown rice removing gutter 15, and also communicates with the lower receiving gutter 12 to transfer the brown rice sorted in each of the above. It is led out to the sorting air path 7 on the rear side of the air selection section B. 17,18
is a paddy return gutter; the paddy return gutter 17 receives the paddy flowing out from the inner peripheral surface of the upper sorting barrel 11 and returns it to the paddy tank 2; The paddy scooped up by the distributed grain lifting bucket 19 is received and returned to the paddy tank 2.

In addition, 20, 20 are upper and lower supply gutter 13,
This is a drop opening for supplying mixed rice to each sorting cylinder 11 by opening the rear side of 13.

21 is a double elevator, which is the front one and is connected to the wind selection section B.
The mixed rice of brown rice and paddy obtained in the above is lifted to the above-mentioned mixed rice distribution box, and the finished brown rice from which waste rice has been removed in the wind sorting section B is taken out to a suitable place outside the machine. .

Next, the configuration of the main part of the present invention will be described.

As shown in FIGS. 1, 2, and 5, the rotary sorting machine C has a front wall 2 formed of a thin iron plate.
2 and the rear wall 23 are connected at the upper part by a canopy 24,
Connect the middle parts on both the left and right sides with connecting plates 25, 25,
The lower sides are connected by lower plates 26, 26 respectively to form a box shape, and between both sides of the canopy 24 and the connecting plates 25, 25, and between the connecting plates 25, 25 and the lower plates 26, 2.
Each cover plate 39 is removably attached between the holes 6 and 6, and is configured in a substantially airtight manner when attached.

Therefore, the above-mentioned upper and lower sorting sections C1 and C2
I have to explain the details of the sorting section C2, but as mentioned above, the sorting barrel 11 of the lower sorting section C2 has the same structure as the upper sorting section C1, except that the fried grain buckets 19 are evenly distributed. C1 will be described, and the lower sorting section C2 will be omitted.

The receiving gutter 12 and the supply gutter 13 of the sorting section C1 are horizontally installed with the front side supported in a cantilever manner on the front wall 22, and the rear side, which is a free end, is supported by cutting out the upper and lower parts of a circular plate. It is integrally fixed to the plate body 27, and the receiving gutter 12
The shaft ends of the screw conveyors 28 and 29 installed in the supply gutter 13 are inserted through and supported by the support plate 27, and the fulcrum shaft end of the gate valve 30 is also supported by the support plate 27.

The rear wall 23 has a large opening that allows the sorting barrel 11 to be freely inserted and removed outside the machine, and this opening and the support plate 27
A shielding plate 31 is fitted between the shielding plate 3 and the shielding plate 31. This shielding plate 31 is tightened and fixed to the rear wall 23 and the support plate body 27 with several knob screws 32, and the support plate body 27 is fixed to the shielding plate 3.
1 to provide strong support.

Further, on the rear side of the sorting cylinder 11 through which mixed rice is supplied from the dropping port 20, an overflow prevention wall 33 is formed by bending the end periphery thereof, and a tongue piece is formed on the inner edge periphery of this overflow prevention wall 33. An elastic annular body 34 made of rubber is integrally fitted into the shielding plate 31, and a cylindrical flange 35 whose outer peripheral surface is joined to the tongue piece of the elastic annular body 34 and is slightly tightened is integrally attached to the shielding plate 31. It is attached to the

Note that 36 and 37 are transparent plates and opaque plates that close the upper and lower cutout portions of the support plate 27, and 38 is the shaft end of the screw conveyors 28, 29 and the fulcrum shaft end of the notch valve 30. It is a box-like cover that covers the

On the lower side of the sorting cylinder 11, two guide rails 40, 4 are provided in the front and back direction as shown in the sorting cylinder 11.
0 are installed horizontally in parallel, and when installing horizontally, the front and rear ends are fixed to the front wall 2 by means of fixed bottles 41, respectively.
2 and the rear wall 23 to connect the front wall 22 and the rear wall 23.

When the sorting cylinder 11 is rotatable with its rolling surface 11a supported by the front and rear wheels 9, 9 and 10, 10, there is a gap between the collar 11b and the guide rail 40 as shown in FIG. is made to have a slight gap M (the rear side is the same, so the illustration is omitted), and the end side of the sorting cylinder 11 has a slightly smaller diameter so as to have a step h with the rolling surface 11a. There is a gap L between the upper edge of the rice-reducing gutter 17 and the height of the flange 11b is H.
The relationship between them is configured as follows: M<L・H>h.

Incidentally, 42 is a gap prevention member such as a sponge that is attached to the upper edge of the paddy reducing gutter 17.

Therefore, when removing the sorting barrel 11 from the machine, first remove the cover 39 from the support plate 27,
Next, after removing the transparent plate 36 and the opaque plate 37, loosen the knob screw 32 and attach the shielding plate 31 to the rear wall 2.
3, the cylindrical flange 35 is also taken out and the rear wall 23 is opened wide.

At this time, the free ends of the receiving gutter 12, the supply gutter 13, and the like are integrally supported by the support plate 27 in a cantilevered manner.

Therefore, if the rear side of the sorting cylinder 11 is lifted a little more than the height of the flange 11b, the front side of the sorting cylinder 11 will be in the state shown in FIG. 7, and the gap prevention body 42 will be slightly compressed. When pulled out rearward, the sorting cylinder 11 becomes the state shown in FIGS. 8 to 9 and is no longer supported by the wheels 9, 9. At the same time, the collar 11b comes into contact with the guide rails 40, 40, and the sorting cylinder 11 is supported. When it is further pulled out from this supported state, the collar portion 11b slides on the guide rails 40, 40, and the sorting cylinder 11 is pulled out of the machine while being supported and guided by the guide rails 40, 40.

In addition, when inserting the extracted sorting barrel 11 into the machine, the flange 11b is connected to the guide rail 40,
If it is inserted while being supported by the guide rails 40, the rolling surface 11a will be placed on the wheels 9, 9, and at the same time, the flange 11b will be inserted into the guide rails 40, 40 and the gap M. Gap prevention body 42
While being slightly compressed, it is supported in a predetermined position and becomes rotatable, and when the shielding plate 31 and the like are sequentially attached, it becomes operational.

Effects of the Invention As described above, the present invention is characterized in that a receiving gutter is inserted into a sorting cylinder that is horizontally hung horizontally so that it can rotate and is supported by a plurality of rollers, with a large number of potholes formed in the inner circumferential surface. In a rotary sorting machine in which the sorting barrel is configured to be removable from the outside of the machine, a guide rail is horizontally installed below the sorting barrel along the sorting barrel, and the guide rail is used to connect the front and rear walls of the machine. Since the sorting cylinder is connected to the main body, the sorting cylinder can be pulled out of the machine or inserted into the machine by sliding on the guide rail while being supported by the guide rail, making the work extremely easy. It can be done conveniently and requires no unnecessary effort and no wasted time when inserting and removing it as in the conventional case.

As a result, it became much easier to clean and inspect the sorting barrel and the inside of the aircraft.

In addition, the upper air guide rail connects the front and rear walls of the fuselage, which strengthens the fuselage and makes it more solid, allowing smooth rotation of the sorting barrel.

As in the example, the gap M between the flange and the guide rail, the level difference h between the rolling surface and the end side, the gap L between the upper edge of the rice-reducing gutter, and the height H of the flange are defined as M If configured as shown in <L・H>h, the sorting cylinder can be inserted and removed by itself by pulling it out and inserting it.Especially when the sorting cylinders are arranged in upper and lower stages, the side where the sorting cylinder is inserted and removed is Although it is inevitable that the rear wall, which is made of thin iron plates, would be weakened, the guide rails could compensate for this weakening and make the fuselage stronger.
